Abstract

A seal for use when inserting a first pipe into a second pipe while maintaining a flow of fluid through the second pipe, the seal being adapted for attachment to the leading portion of the first pipe to temporarily seal the first pipe during insertion of the first pipe to prevent fluid flow along the first pipe until the first pipe has been inserted. The seal has a rupturable membrane or removable plug 28 to temporarily seal the first pipe. Spacers 29 - 33 are provided to guide the seal in the second pipe, the spacers having apertures 34 to allow fluid to flow in the space between the pipes. Alternatively the spacers may be flexible to allow fluid flow. <IMAGE>
